System Overview
The “XSSET-1” is a precise single stage “G-SWITCH” activated timing and control
system. Time and mode settings are set using a six-position DIP switch that eases
programming the unit. It runs off of an external DC power supply ranging from +7V to
+15V. Other applications such as relay switching and solenoid driving can also be
implemented using the “XSSET-1”. Various electric matches may be used because of
the versatility and high current FETs used in the design of the “XSSET-1”; these include,
but are not limited to; Quickburst, Daveyfire and OXRAL.

Figure 2 gives a close look at the DIP switches and explains the time value of each
switch. Table 1 gives examples of a few settings. For example, to get a delay of 10
seconds you would turn ON switch 2 and switch 4 (2 seconds + 8 seconds = 10
seconds), the rest would be OFF. Figure 3 gives you switch examples for both modes of
operation.

** IMPORTANT**: Switches MUST be set prior to turning power on to
“XSSET-1”. The microcontroller ONLY reads the switch settings on
power up. If changes need to be made, turn unit OFF, set switches,
and cycle power back ON.

“XSSET-1” MODES:
The “XSSET-1” has 2 modes of operation, “TMR” (TIMER) and “BOS” (BURN-OUT
SENSE). In “TMR” mode the unit begins countdown as soon as the “G-SWITCH” is
CLOSED (launched). In “BOS” mode the unit begins countdown after the “G-SWITCH”
has CLOSED and OPENED (motor burns out). For both modes we do a 0.5s sample
of the “G-SWITCH” to help prevent a misfire by someone “bumping” the rocket. The
“TMR” and “BOS” modes are chosen by the sixth (position 6) DIP switch. When the
switch is OFF the unit is in “TMR” mode and when the switch is ON the unit is in “BOS”
mode. Figure 4 shows DIP switch values.

The “BOS” mode is especially useful for parachute / streamer deployment. You set the
timer for how long after the motor has burned out you want to wait before igniting your
charge. The “TMR” mode is useful if you want to either air start motors (cluster) or ignite
a secondary stage of your rocket. You set the dip switches for how long you want to wait
after the rocket is launched before you activate your charge.

Pyrotechnic Installation:
The “XSSET-1” has been tested using various igniters and electric matches. To install a
pyrotechnic device onto the “XSSET-1” (power needs to be OFF), you simply unscrew the
terminals located as in figure 7. The terminals are screw based terminal blocks for easy access
and reliability. User does not need to worry about which terminal goes to which leg of the igniter /
electric match. Make sure you hand tighten ONLY (too much torque can damage the unit)
screw terminals after igniter / electric match has been installed.

<-Recommended igniter / electric matches:
The “XMFT-1” has been tested using the Quickburst “HOT SHOT”, Daveyfire and OXRAL electric
matches. It is always recommended that you “dip” your e-matches into pyrogen to help with motor
ignition. It is recommended that you test the model you are using to insure proper ignition occurs.
We here at XAVIEN have used electric matches that are easily available to us for testing. If you
are using something different than what is listed and want to make sure it will work before buying
a “XMFT-1” email us, and we will look into testing a unit using your model of electric match. Our
time is limited so no guarantees on how fast we can do this.

Battery Connections:
The “XSSET-1” was designed to operate using a 9V alkaline battery. We here at XAVIEN
recommend using a switch to insure ease of use when powering the unit up and down. We have
equipped the unit with a small green power indicator so the user can easily identify when the unit
has power applied. It is recommended that the user do tests using their igniter / electric match
configurations before “assuming” anything will work. This will help to insure that the “XSSET-1”
and your configuration will work to your expectations. In figure 8 we have a basic diagram of the
battery connections that are recommended by us. It is always a good idea to insure you have
a fresh (new) battery before any launches occur. After all, the cost of a battery is nothing
compared to the time and money spent on many of our users rockets.

Setup Sequence:
This is the recommended sequence for setting up the “XSSET-1”.
1. Make sure unit is NOT powered up, if it is turn it OFF,
2. Set DIP switches to desired time delay.
3. Install igniter / electric match, making sure screw terminals are not loose, hand
tighten only.
4. Install a fresh 9V battery, making sure screw terminals are not loose, hand tighten
only. Reversing the polarity of the battery can damage the “XSSET-1”, when
installing the battery refer to figure 8 for the correct polarity.
5. Turn “POWER” on to XSSET-1; verify that the GREEN (“POWER”) LED and the RED
(“CONTINUITY”) LED’s are ON. If the RED LED is OFF you have a continuity issue
with your pyro, if the GREEN LED is OFF, you have a power problem. If both LED’s
are on, unit is ready for launch!

Mounting / Installation
The “XSSET-1” must be installed securely to prevent the unit from being damaged during use.
Since this unit does depend on a “G-SWITCH”, orientation of the unit is very important, the
“arrow” must be pointing in the direction of travel. The mounting holes are 0.125”; this allows
various size screws to be used. Just verify the clearance of both the screw and the head to insure
a proper fit without damaging the unit.

(3.175mm)
2.5" (63.5mm)

URGENT: The “XSSET-1” MUST be protected from ejection
charge and motor residue. These are corrosive and over time
can damage the “XSSET-1”. If this occurs, the warranty does
not cover this type of damage. It is good practice to clean the
unit using Isopropyl Alcohol (70% alcohol or better).

** Handling Precautions **
These units are sensitive to damage from ESD and should always be handled in a properly
grounded environment; damage from ESD is not covered under the warranty. Never transport or
handle a rocket with an “XSSET-1” that is powered up and connected to live pyrotechnic charges.
When installing electric matches in a “XSSET-1”, make sure unit is powered off. Before launching
verify that the RED “CONTINUITY” LED is on.
